UNITED STATES PATENT OEEICE.

JOSEF PISSINGER, OF MUNICI-I, GERMANY.

WATER-GAGE GLASS.

SPECIFICATION forming part of Letters Patent No. 572,181, dated December 1, 1896.

Application filed Januaryll, 1896. Renewed October 14, 1896. Serial No. 608,892.

gage-glass with its center broken away, the

upper ends of the parts being in section.

The glass is shown at s and is centrally arranged, being protected by a cage composed of a series of bars o, joined at their upper and lower ends to rings 0. A box p closes the lower end of the ring o, (see upper part of the iigure,) and this box has a central opening receiving the end of the glass s. A y

packing-screw q closes the upper end of the ring, and between the box p and screw q is inserted the packing 1, thus making a tight connection. The screw or plug q has a projecting nipple fitting within the end of the (No model.) Patented in Germany June glass s, thus keeping the passage clear. The upper face of the plug q is formed concave to receive the convex face of the partt,

which is screwed into the stufng-box ring u', supported in the head w. The concavo-convex connection prevents leakage even when the parts are not exactly in alinement. The parts are readily detachable to remove the glass when broken and insert a new one.

I claim- In combination, the nipples havin g rounded bearing ends, the glass tubes and the carrier-frame therefor comprising the parts q having rounded bearings adapted to the nipples t, the boxes p, the rings o to which the boxes and parts q are attached and the protecting-rods V extending alongside the glass tube and connected to the rings o, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

JOSEF PISSINGER.
